"Wireless communications systems operating in the 60 GHz band take advantage of the high absorption caused by oxygen, which limits signal propagation to a few feet, thus reducing interference to/from other neighbor wireless systems.The WiGig specification will allow devices to communicate without wires at gigabit speeds within a typical room."

It still seems like a pretty cool technology though. The only way I could see this being used instead of the original Wifi standards (in the 2- 5ghz range), is if you built a pico cell style extended service set. But that seems like it would be ridiculously expensive to implement.
